DETAILED DESCRIPTION
[0014] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.
[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0016] See also Figure 1 as well as Figure 2The present embodiment provides a safety fireproof distribution cabinet for electrical construction, including a cabinet body 10, a piston assembly 20, an airbag 30 and a detection assembly 50. A cabinet door 101 is arranged on one side of the cabinet body 10. A partition 102 is fixedly arranged on the top of the inner side of the cabinet body 10. The piston assembly 20 is arranged on the upper part of the partition 102. An expansion medium is arranged on one side of the piston assembly 20. The airbag 30 is provided with a plurality of groups. The plurality of airbags 30 are vertically distributed below the partition 102 and are connected in sequence. The upper group of airbags 30 is connected to the area above the partition 102. The detection component 50 is installed on the inner side wall of the cabinet 10 to detect the internal temperature of the cabinet 10. When the temperature of the cabinet 10 rises due to a fire in the electrical components inside the cabinet 10, the detection component 50 is used to control the piston assembly 20 to move along the upper part of the partition 102 to pressurize the expansion medium into the interior of the several airbags 30, thereby driving the several airbags 30 to expand and cover the outside of the electrical components.
[0017] When there is no fire inside the cabinet 10, the piston assembly 20 is stationary at a certain position on the upper part of the partition 102, and the airbags 30 are in a deflated state. When the electrical components inside the cabinet 10 catch fire due to aging or short circuit, the detection assembly 50 detects that the temperature inside the cabinet 10 has increased, and then controls the piston assembly 20 to move along the upper part of the partition 102 to pressurize the expansion medium into the airbags 30, thereby driving the airbags 30 to expand. When the airbags 30 expand, they can cover the outside of the electrical components and fit tightly to the electrical components, so that there is no air outside the electrical components for continued combustion, thereby achieving the purpose of rapid fire extinguishing.
[0018] See also Figure 1 as well as Figure 3In one embodiment, the piston assembly 20 includes a first electromagnetic adsorption plate 201, a permanent magnet plate 202, a piston plate 203 and an elastic member 204. The first electromagnetic adsorption plate 201 is fixedly mounted on the inner wall of the cabinet 10. The piston plate 203 is arranged on one side of the first electromagnetic adsorption plate 201. The bottom of the piston plate 203 contacts the upper surface of the partition 102. The upper part of the piston plate 203 contacts the inner top wall of the cabinet 10. The permanent magnet plate 202 is arranged on the side of the piston plate 203 facing the first electromagnetic adsorption plate 201. One end of the elastic member 204 is connected to the side of the piston plate 203 away from the first electromagnetic adsorption plate 201, and the other end is connected to the inner wall of the cabinet 10, which is used to provide elastic tension to the piston plate 203. The detection component 50 includes It includes a first conductive rod 501, a first conductive block 503, a conductive contact piece 504, a column 507, a column 508 and a temperature-sensitive balloon 509. One end of the first conductive rod 501 is connected to the first electromagnetic adsorption plate 501, and the other end extends to the bottom of the partition 102 and is connected to the first conductive block 503. The conductive contact piece 504 is attached to one side of the first conductive block 503. The column 507 is fixedly installed on the inner wall of the cabinet 10. The temperature-sensitive balloon 509 is arranged at the bottom of the column 507. Mercury is contained in the temperature-sensitive balloon 509. The column 508 is movably arranged in the column 507. The upper end of the column 508 is connected to the conductive contact piece 504 through a push rod 506. The conductive contact piece 504 is also connected to an external power supply through a wire (not shown in the figure).
[0019] Initially, the conductive contact piece 504 is attached to one side of the first conductive block 503, and the external power supply supplies power to the first electromagnetic adsorption plate 201 through the wire, the conductive contact piece 504, the first conductive block 503 and the first conductive rod 501. The first electromagnetic adsorption plate 201 supplies power to generate magnetism, and then generates magnetic attraction to the permanent magnet 202, so that the piston plate 203 is located at a certain position on the upper part of the partition 102 and remains stationary. At this time, the elastic member 204 is in a stretched state. When the electrical components inside the cabinet 10 catch fire, the temperature inside the cabinet 10 rises sharply, and the mercury in the temperature-sensing balloon 509 expands toward the inside of the column 507 due to the high temperature, thereby pushing The column rod 508 rises along the inside of the column tube 507. When the column rod 508 rises, the push rod 506 pushes the conductive contact piece 504 upward, so that the conductive contact piece 504 is separated from the first conductive block 503, and the power supply between the external power supply and the first electromagnetic adsorption plate 201 is cut off. The first electromagnetic adsorption plate 201 no longer provides suction to the permanent magnet plate 202, and the elastic member 204 pulls the piston plate 203 so that the piston plate 203 moves along the upper part of the partition 102, and then presses the expansion medium into the interior of the plurality of airbags 30, so that the plurality of airbags 30 expand and cover the outside of the electrical components, thereby isolating the air outside the electrical components and realizing rapid fire extinguishing of the electrical components.
[0020] See also Figure 1 as well as Figure 2 In one embodiment, two adjacent groups of the inflatable airbags 30 are connected via a flexible air tube 301, and the top group of the airbags 30 is connected to the upper area of the partition 102 via a hard air tube 303, and the hard air tube 303 is fixedly mounted on the bottom wall of the partition 102.
[0021] When a fire occurs in electrical components inside the cabinet 10 and causes the piston plate 203 to move along the upper part of the partition 102, the piston plate 203 presses the expansion medium to the topmost airbag 30 via the hard air tube 303, and then presses it to the remaining airbags 30 in turn via a plurality of flexible air tubes 301, thereby driving all the airbags 30 to expand and deform. When all the airbags 30 expand and deform, they can indiscriminately cover all electrical components inside the cabinet 10, thereby achieving the purpose of rapid fire extinguishing.
[0022] In one embodiment, the airbag 30 is made of fireproof material. When the airbag 30 is expanded and covers the burning electrical components, the burning electrical components can be effectively prevented from igniting the airbag 30, thereby improving the fire extinguishing effect.
[0023] In one embodiment, the hard air tube 303 may be a metal air tube or a plastic air tube, which is not limited here.
[0024] In one embodiment, the expansion medium can be air or water, which is not limited here. When the expansion medium is water, the piston plate 203 sends water pressure to the interior of the plurality of airbags 30 to expand the plurality of airbags 30. The expanded airbags 30 cover the outside of the electrical components that are on fire. On the one hand, the airbags 30 can isolate the air outside the electrical components to achieve preliminary fire extinguishing of the electrical components. On the other hand, the water inside the airbags 30 can also achieve cooling treatment of the electrical components, thereby achieving further fire extinguishing of the electrical components.
[0025] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment, a second electromagnetic adsorption plate 40 is embedded at the bottom of the partition 102, and an iron ring 302 is also arranged on the outside of the flexible air tubes 301. The detection component 50 also includes a second conductive rod 502 and a second conductive block 505. The second conductive block 505 is arranged on the side of the conductive contact piece 504 away from the first conductive block 503 and is attached to the conductive contact piece 504. One end of the second conductive rod 502 is connected to the second conductive block 505, and the other end is connected to the second electromagnetic adsorption plate 40.
[0026] Initially, one end of the conductive contact piece 504 contacts the first conductive block 503, and the other end contacts the second conductive block 505. On the one hand, the external power supply supplies power to the first electromagnetic adsorption plate 201 through the wire, the conductive contact piece 504, the first conductive block 503 and the first conductive rod 501, and the magnetic attraction between the first electromagnetic adsorption plate 201 and the permanent magnet plate 202 makes the piston plate 203 stationary at a certain position on the upper part of the partition 102. On the other hand, the external power supply can also supply power to the second electromagnetic adsorption plate 40 through the wire, the conductive contact piece 504, the second conductive block 505 and the second conductive rod 502, so that the second electromagnetic adsorption plate 40 is powered and magnetized, and then the plurality of iron rings 302 are adsorbed at the bottom of the partition 102. When the plurality of iron rings 302 are adsorbed at the bottom of the partition 102, the corresponding plurality of air bags 303 can be simultaneously confined at the bottom of the partition 102. The storage of several airbags 303 is realized; when the electrical components inside the cabinet 10 catch fire and cause the conductive contact 504 to move upward, the conductive contact 504 is separated from the first conductive block 503 and the second conductive block 505 at the same time, and the first electromagnetic adsorption plate 201 and the second electromagnetic adsorption plate 40 are powered off synchronously. After the second electromagnetic adsorption plate 40 is powered off, it no longer provides suction to the several iron rings 302, and the several iron rings 302 fall from the bottom of the partition 102 by themselves, thereby driving the several airbags 30 to fall by themselves, so that the several airbags 30 remain in a natural drooping state. After the first electromagnetic adsorption plate 201 is powered off, it no longer provides magnetic suction to the permanent magnet plate 202, and the elastic member 204 pulls the piston plate 203 to move, so as to press the expansion medium into the several airbags 30 in the drooping state, so that the several airbags 30 expand and deform and cover the outside of the electrical components, thereby realizing the fire extinguishing of the electrical components.
[0027] In one embodiment, the elastic member 204 may be a spring or a metal spring, which is not limited here.
[0028] See also Figure 1 as well as Figure 2 In one embodiment, a ventilation hole 103 is further provided on the side wall of the cabinet 10 .
[0029] By setting the vents 103, ventilation inside the cabinet 10 can be achieved, and when the air bags 30 expand and cover the outside of the electrical components, the air bags 30 can also press the air inside the cabinet 10 to the outside of the cabinet 10 through the vents 103, thereby achieving rapid discharge of the air inside the cabinet 10.
[0030] In the embodiment of the present invention, when there is no fire inside the cabinet 10, the piston assembly 20 is stationary at a certain position on the upper part of the partition 102, and the plurality of airbags 30 are in a deflated state. When the electrical components inside the cabinet 10 catch fire due to aging or short circuit, the detection assembly 50 detects that the temperature inside the cabinet 10 has increased, and then controls the piston assembly 20 to move along the upper part of the partition 102 to pressurize the expansion medium into the plurality of airbags 30, thereby driving the plurality of airbags 30 to expand. When the plurality of airbags 30 expand, they can cover the outside of the electrical components and fit tightly to the electrical components, so that there is no air on the outside of the electrical components for continued combustion, thereby achieving the purpose of rapid fire extinguishing. Compared with the prior art, when an electrical component inside the distribution cabinet catches fire, the electrical component can be automatically extinguished, and the remaining electrical components that have not caught fire will not be damaged during the fire extinguishing process, thereby reducing losses and improving the fire extinguishing effect.
[0031] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
